Thread: Question on bleeding CTS-V Brakes

Hey guys, while my car was under the knife this past weekend, I had to open the bleeder screw on my passenger front caliper to get it back over the Rotor. I'm going to bleed the brakes tonight, but do I have to do all 4 corners, or can I just do the Fronts? I read somewhere that the master cylinder is split into 2 (Front and back).

Any help is appreciated. Thanks!

you can do just that caliper if you like. you only opened the one it seems. why im not sure. you can C clamp the pistons to make them open up with the bleeder closed, the fluid just pushes back up to the master's res.

I tried, but it was rock hard and the clamp was starting to take the powder coating off. So I just unscrewed the bleeder and pushed the piston down. I'll just do the one I cracked (maybe the 2 fronts). I just didn't want to have to do all 4...

thanks man.

oh, that pretty finish. i hear ya. they sell a tool for like 10 bucks, works on the inside, it dont touch the outside finish.

Hold on you couldn't get the piston pushed back in even with a c-clamp?.. you should be able to push them in with your hand.. did you take the cap off the brake fluid reservoir?
